[Matlab] Plotting a function inside a m-file?

  1. Oct 9, 2012 #1
    A3.m:

    %x = 0:pi/100:2*pi;
    %y = sin(2*x);
    %z = 2*cos(2*x);
    %plot(x,y,'k',x,z,'--b')
    %title('Plot of f(x)=sin(x) and it''s derivative')
    %xlabel('X-axis')
    %ylabel('Y-axis')
    %legend('sin(2x)','2cos(2x)')
    x = -2:0.01:2
    y = f2(x)
    plot(x,y)

    f2.m:

    function F = f2(x)
    F(1) = 2*(x(1)^4)-3*(x(1)^2)+x(1)-7;

    I ran A3.m but it doesn't seem to create a correct plot.
